d18O (permil)

TSid: TR04EVLI01

variableName: d18O

units: permil

description: cellulose

interpretation
1

basis: The range of the observed 18O cyclicity, 3a€“5a€°, is approximately equal to the annual range of observed rainfall d18O values (IAEA/WMO, 2003) for stations from Honduras, Costa Rica and Panama.

variable: precipitation

4

basis: Sub-annual cyclic isotopic signatures of several permil represent the annual cycle of local rainfall and relative humidity. Additional data from a plantation tree of known age from ENSO-sensitive northwestern coastal Peru suggests that the 1997–8 ENSO warm phase event was recorded as an 8‰ anomaly in the δ18O of α-cellulose.
